Issue 8 (April 2011)

From early on we can see that the middle box is the “busiest”. We can see that the numbers missing from that box are 4, 6 and 8.

6 has to be in the middle box as the other 2 boxes already have a 6 on their respective lines.

Once the 6 is in place, the 4 can only be on the top line of that box as the other box has a 4 already on its column.

Then, the 8 has to be in the remaining square to finish the box. Continue on and have fun.

Good luck.
